‘Nocturne’s Perfect Imagine Dragons Needle Drop Explained By Rory Culkin, Show’s EP

In Apple TV thriller *Nocturne*, Karl Anders’s favourite song, Imagine Dragons’ “Radioactive”, returns in Episode 4 as he drives off to deliver a note to Jurek’s lawyer. The scene pays off a detail from Episode 2 and accompanies Karl’s decision to defy the system, suggesting a new confidence and connection with Jurek.

Co-showrunner John Hlavin said his daughter’s enthusiasm for the song meant he had heard it countless times and wanted that familiarity to pay off in the story; he chose it because it was catchy, not as a joke. Rory Culkin listened to the track while filming and said viewers could decide what it reveals about Karl. The scene also features Karl’s politically themed bumper stickers and a 1992 Pontiac Firebird.
